    Notes: Summary A sensitive method has been developed for the quantitation of small amounts of SV40 cRNA by means of competition hybridization of3H-SV40 cRNA (transcribed in vitro with RNA polymerase fromE. coli). The rate of competition is only slightly diminished by a moderate excess of filter-bound SV40 DNA. By using a tenfold excess of SV 40 DNA and a3H-SV40 cRNA of high specific activity it is possible to obtain a competition rate of 50% with only ng amounts of unlabelled SV40 cRNA.

    Description / Table of Contents: Zusammenfassung Der ImmunoCombChlamydia trachomatis IgG/IgA (Orgenics, Israel) ist ein neuer serologischer Test, derC. trachomatis L2 Elementarkörperchen (Washington Research Foundation, Seattle) als Antigen verwendet. Beim Ipazyme IgG/IgA Test (Savyon, Israel) dienenC. trachomatis-L2-Einschlüsse infizierter Zellen als Antigen, das heißt Elementar- und Retikulärkörperchen. Theoretisch sind beim ImmunoComb weniger Kreuzreaktionen (LPS) mitChlamydia pneumoniae zu erwarten als beim Ipazyme Test (LPS und gruppenspezifische Retikulärkörperchen-Antigene). In einer Kontrollgruppe von 100 Wöchnerinnen mit einer 6%-Prävalenz anC. trachomatis-positiven Zervixabstrichen zeigte der ImmunoComb-IgA im Vergleich zum Ipazyme sowohl einen höheren positiven Vorhersagewert (36% gegenüber 25%) als auch eine höhere Sensitivität (67% gegenüber 33%) für den Antigennachweis. Bei Sterilitätspatientinnen (45 Fälle mit verschlossenen und 53 mit offenen Tuben) betrugen die Werte in bezug auf die Vorhersage des Tubenstatus beim ImmunoComb (Ipazyme) 74% (72%) für den positiven Vorhersagewert, 87% (80%) für die Sensitivität und 87% (81%) für den negativen Vorhersagewert. 118 Patientinnen mitC. trachomatis-positivem Zervixabstrich zeigten im ImmunoComb eine IgG/IgA Prävalenz von 85%/55% verglichen mit 84%/49% im Ipazyme. Der ImmunoComb ist beträchtlich schneller und einfacher in der Handhabung und weniger subjektiv in der Ablesung als der Ipazyme.
    Notes: Summary The ImmunoCombChlamydia trachomatis IgG/IgA (Orgenics, Israel) is a new serologic test usingC. trachomatis L2 elementary bodies (Washington Research Foundation, Seattle) as antigen. The Ipazyme IgG/IgA test (Savyon, Israel) employs whole cells withC. trachomatis L2 inclusions, i. e. elementary and reticulate bodies. Theoretically, the ImmunoComb is expected to be less cross-reactive (LPS) withChlamydia pneumoniae than the Ipazyme (LPS and reticulate body group specific antigens). Compared with the Ipazyme, the ImmunoComb IgA showed both a higher positive predictive value (36% versus 25%) and sensitivity (67% versus 33%) for antigen detection in a control group of 100 post partum women with a 6% prevalence ofC. trachomatis positive cervical smears. In sterility patients (45 cases with occluded and 53 with open fallopian tubes) the tube status was predicted by the ImmunoComb (Ipazyme) with 74% (72%) positive predictive value, 87% (80%) sensitivity, and 87% (81%) negative predictive value. IgG/IgA prevalence in 118 patients withC. trachomatis positive cervical smears was 85%/55% for the ImmunoComb and 84%/49% for the Ipazyme. The ImmunoComb is considerably faster and easier in handling and less subjective in reading than the Ipazyme.

    Description / Table of Contents: Zusammenfassung Der ImmunoComb® Chlamydia Bivalent IgG/IgA (Orgenics, Israel) ist ein neuer serologischer Test, der LPS extrahierteChlamydia trachomatis L2 und LPS extrahierteChlamydia pneumoniae Elementarkörperchen auf zwei getrennten Antigenpunkten verwendet. Die BivalentC. trachomatis spezifischen Testergebnisse wurden mit dem Mikroimmunfluoreszenztest (MIF), dem Goldstandard der spezies-spezifischen Chlamydienserologie, verglichen. In Bezug aufC. trachomatis IgG zeigte der Bivalent hohe Übereinstimmung mit dem MIF: Der Anteil positiver Titer (IgG ≥ 1:8) lag bei 10% vs. 11% bei 100 Blutspendern, 18% vs. 16% bei 111 Wöchnerinnen (6% Antigenprävalenz), 26% vs. 22% bei sterilen Frauen mit offenen (n=54) und 86% vs. 84% mit verschlossenen (n=51) Tuben und 88% vs. 85% bei 103 Frauen mitC. trachomatis positivem Zervixabstrich. Überraschenderweise zeigten Bivalent und MiF sehr unterschiedliche IgA Prävalenzen: bei Wöchnerinnen (8% vs. 4%), sterilen Frauen mit offenen (13% vs. 6%) und verschlossenen (71% vs. 20%) Tuben und Frauen mit positivem Zervixabstrich (78% vs. 24%). Der Bivalent IgA Test zeigte sich sensitiver als der MIF IgA bei gleichzeitig höherer Korrelation zu positivem Zervixabstrich bei Wöchnerinnen (Sensitivität 67% vs. 0%, Spezifität 95% vs. 96%, positive Vorhersage 44% vs. 0%, negative Vorhersage 98% vs. 94%) und zum Tubenverschluß bei sterilen Frauen (Sensitivität 71% vs. 20%, Spezifität 87% vs. 94%, positive Vorhersage 84% vs. 77%, negative Vorhersage 76% vs. 55%). MIF IgM erwies sich als diagnostisch wenig hilfreich. Als Ergänzung zum oft schwierigenC. trachomatis Antigennachweis erscheint der einfach durchzuführende Bivalent IgG/IgA als sehr nützlich in der Routinediagnostik genitaler Chlamydieninfektionen.
    Notes: Summary The ImmunoComb® Chlamydia Bivalent IgG/IgA (Orgenics, Israel) is a new quantitative serologic test that employs LPS extractedChlamydia trachomatis L2 and LPS extractedChlamydia pneumoniae elementary bodies on two separate antigenic spots. The BivalentC. trachomatis specific test results were compared with microimmunofluorescence (MIF), the gold standard of chlamydial species specific serology. ForC. trachomatis IgG the Bivalent was highly concordant with the MIF: the rate of positive titres (IgG≥1:8) was 10% vs. 11% in 100 blood donors, 18% vs. 16% in 111 obstetric patients (6% antigen prevalence), 26% vs. 22% in sterile women with open (n=54) and 86% vs. 84% with occluded (n=51) tubes, and 88% vs. 85% in 103 women withC. trachomatis positive cervical smears. Surprisingly, the Bivalent differed considerably from the MIF in IgA prevalence: in obstetric patients (8% vs. 4%), sterile women with open (13% vs. 6%) and occluded (71% vs. 20%) tubes, and women with positive cervical smears (78% vs. 24%). Bivalent IgA appeared to be more sensitive than MIF IgA and showed a stronger correlation with positive cervical smears in obstetric patients (sensitivity 67% vs. 0%, specificity 95% vs. 96%, positive prediction 44% vs. 0%, negative prediction 98% vs. 94%) and with tubal occlusion in sterile women (sensitivity 71% vs. 20%, specificity 87% vs. 94%, positive prediction 84% vs. 77%, negative prediction 76% vs. 55%). MIF IgM was of little diagnostic help. Supplemental to the often difficultC. trachomatis antigen detection, the easily performed Bivalent IgG/IgA appears to be of great value in routine diagnosis of genital chlamydial infections.
